JAMES I. KINKEAD, OF SAN FRANCISCO, CALIFORNIA.

PORTABLE WINDLASS.

SPECIFICATION forming part of Letters Patent No. 429,242, dated June 3, 1890.

Application filed December 18, 1839. Serial No. 334,207. (No model.)

To all whom t may concern:

Be it known that I, JAMES I. KINKEAD, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Portable Windlasses; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device which I call a portable windlass, which is designed to take the place of blocks and tackle, and which may be used for the application of power to move loads.

It consists of a light frame of iron, steel, or other metal, having the windlass-shaft journaled across it near the center, with suitable crank attachments and guides formed integral with the frame, through which the rope passes, together with swivel attachments for anchoring ropes or chains, and certain details of construction.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a plan view of my windlass. Fig. 2 is a side elevation.

A A are the side pieces of my windlassframe. These are preferably made convex in form, with the concave faces directed toward each other, and across the widest portion is journaled the windlass-shaft B, having keyed or otherwise secured to it the drum C. The shaft is journaled in suitable boxes upon the sides A, and may either extend outwardly beyond the sides and have cranks fixed upon its end, or, as shown in the pres' ent drawings, a second or counter shaft D is journaled upon the frame parallel with the shaft B, having a pinion E, which engages with the gear F, fixed upon the drum-shaft. Cranks or other driving devices G may be ixed'to the outer end of the counter-shaft, so that power may be applied to rotate the windlass-drum. At the ends the sides A are united with the transverse plates II, which extend across parallel with the windlass shaft, and they have slots I made horizontally in them and in line with the periphery of the windlass-drum, so that the rope J passes in through one of the slots, and after a sufficient number of turns have been carried about the drum C the opposite end of the rope is carried out through the slot I at the opposite end of the frame,'these slots serving as guides to keep the rope in line and prevent its working off of the drum.

The sides A may be stamped of wrought metal, and afterward riveted or otherwise united to the ends II; but I have found it preferable to cast the whole of steel, malleable iron, or other metal of sufficient strength and lightness, so that the frame is all formed in one rigid piece.

At each end of the end plates II is fixed a swivel or shackle K, and to these shackles are connected ropes or chains L, by which the frame may be anchored at any desired point. If it is desired to haul logs or other heavy bodies, supposing the direction of movement to be as shown by the arrow in the figure, the rope, passing through the slot I in one end of the frame, is passed around the windlass-drum C a sufficient number of turns to prevent slipping, and is then carried out through the slot I at the opposite end of the frame.

By means of the shackles, and chains at the rear end of the frame it may be anchored or attached to any suitable holdingpoint, and power being applied to the windlass-drum the rope will be wound around from the front and delivered through the rear end. If the weightis sufficient to make it necessary to use block and tackle, the rope, Aforming what is known as the 'fall, maybe passed around, the windlass. By this construction I am enabled to make a light portable Windlass, which may be carried from place to place in the hand 4in thesame manner as the block and tackle, the device being easily fixed and applied for the purpose of transmitting power.

Having thus described my invention, what I claim as new, and desire to secure by Let-ters Patent, is

An improved windlass consisting of a frame having curved sides and slotted end pieces uniting the sides, a winding-drum mounted on a shaft journaled across the side pieces of the frame, n tangent to said drum ferxn- In Witness whereof I have hereunto set my ing a line between the slots in the end pieces, hand. wherebyn the rope will be reeeiffed upen {L'nd JAMES L KINKEAD. dehvered from the drum W1th0ut frletlon upon the walls 0f the slots, and shackles at XVtneSSes: the ends 0f the end pieces for anchoring the GEO.

frame, substantially as described.
